AI overview
A greenish warbler is a small songbird found across Asia that has become famous among scientists as a key example of how new bird species evolve and diverge from a common ancestor. Researchers have extensively studied populations of these warblers across different regions to understand how geographic separation and isolation lead to the development of distinct species over time.

The greenish warbler (Phylloscopus trochiloides) is a widespread leaf warbler with a breeding range in northeastern Europe, and temperate to subtropical continental Asia. This warbler is strongly migratory and winters in India. It is not uncommon as a spring or early autumn vagrant in Western Europe and is annually seen in Great Britain. In Central Europe large numbers of vagrant birds are encountered in some years; some of these may stay to breed, as a handful of pairs does each year in Germany.
Like all leaf warblers, it was formerly placed in the "Old World warbler" assemblage, but now belongs to the new leaf-warbler family Phylloscopidae. The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific trochiloides is from Ancient Greek trokhalos, "bowed", and -oides "resembling", from the similarity to the willow warbler, P. trochilus. The English name of this species provides a perfect argument in favour of the capitalisation of species names (i.e. treating them as proper nouns), a convention which is generally applied in scientific literature. The decapitalised "greenish warbler" is equally descriptive of many bird species across multiple families, whereas a capitalised "Greenish Warbler" shows unambiguously that Phylloscopus trochiloides is under discussion.
